testpscad用以通过matlab来调用PSCAD程序，并执行PSCAD的模型，结束后关闭程序； testwrite是对PSCAD的模型进行修改的一个例子(testpscad matlab to call for the adoption of PSCAD program, and execute PSCAD model, after the close of the program testwrite PSCAD model is an example of modification)

该代码是用MATLAB代码写出，用于生成格雷码，得到物体的三维信息(The code is written in MATLAB code，Used to generate the Gray code, get the object three-dimensional information)

机器人仿真程序，有界面和运行系统，供初学者学习(robot simulator，just for preliminary learner to study。Thank you very much。haha )

本手册的研究内容主要有Kalman滤波，扩展Kalman滤波，无迹Kalman滤波等，包括理论介绍和MATLAB源程序两部分。本手册所介绍的线性滤波器，主要是Kalman滤波和α-β滤波，交互多模型Kalman滤波，这些算法的应用领域主要有温度测量、自由落体，GPS导航、石油地震勘探、视频图像中的目标检测和跟踪(kalman and Application)

根据德布鲁意序列，编写的MATLAB代码，生成伪随机序列，继而转化为图片，图片中一定大小的图像块与其他任何相同大小的图像块都不同。(According to the de Bruges sequence, the MATLAB code is written to generate a pseudo-random sequence, which is then transformed into a picture in which a certain size of the image block is different any other image block of the same size.)

快速计算一维信号的塔式谱峭度图，选择谱峭度最大值区间，方便确定所需滤波器中心频率及带宽。(Computes the fast kurtogram of signal x.This fast algorithm uses a pyramidal decomposition of the signal into a user-specified number of levels (a good choice is nlevel = 8). The first level is the classical kurtosis of the signal, the second level is the spectral kurtosis in 2 octaves, the third level the spectral kurtosis in 4 half-octaves, etc. Non-integer levels refer to divisions into third octaves. Here below is an illustration on how the frequency band is successively split when increasing the level)
